okay i must be the only idiot that's having trouble depining my sensors. im trying to re sleeve my harness, nothing major just cleaning it up a bit. I cant for the life of me figure out how to depin the connectors! ive seen pics and have been watching youtube videos for hours but every time they go to demonstrate they turn the connector away from the video. i just watched about 20 videos lol and this guy just inserted a paperclip in the connector and the pin came right out, that was the final straw that pissed me off. i can build my motor from the ground up, i can do all my body work. But for the life of me i cant depin a damn connector!!

i went out and bout a set of micro precision flatheads drivers so im sure i have the right tools. i just need to know where to insert the screwdriver to depress the clip thats holding the pin in.

btw ive been all through signalpukes diy threads, yes ive checked/seen the pics, yes im still dumb enough and need more help. i guess theres no hope for me haha

thanx in advance for any help

This is how the pin is being held in the plug. Insert the paper clip (blue in the diagram) from the front at a angle and feel for the catch (black) , lift it up and u will be able to remove the pin easily.

some pins i had to push forward slightly to get my tool to pick it loose then after you "feel" it liftiing up i slide the pin out the plug

Here is a quick and dirty DIY on how to de-pin your injector connectors.

Tools,
Image


Needle Nose pliers and a long small prying tool. A watch makers screwdriver is the best tool. I made my own to fit in to all different connector pin locks. I ground off the end of an old style xmas ornament hook. This one is strong enough that I can put pressure on it and it does not kink/bend in half. It will break before it bends.

On the wire side of your injector connector you should see a small plastic tab sticking out from the rubber seal. Similar to this.

Image


You take your needle nose pliers and grasp the plastic tab. Like so.

Image


With the connector in one had and your pliers in the other. Firmly pull the pliers away from the connector.

Image


If your connectors do not have this plastic tab you should just be able to pull the rubber plug out of the connector with your pliers and or pry it out with a small screwdriver.

Once you have the rubber gasket free from the connector slide it down the wires enough to give you some room to handle the wires individually.

Image


Above is a view of the connector where you will be releasing the pin lock with your trusty screwdriver or pin tool.

With your tool in hand push it into the hole directly below the pin. Like this.

Image


Once you feel your tool hit the back or tab of the connector gently pry downward on your tool forcing the tip of the tool up against the pin. At the same time you should be gently pulling on the corresponding wire.

Image


It's a bit tricky to pry and pull at the same time. With practice it becomes quite easy to do. If you can place the connector in a vice that will make it a lot easier.

You may have to push the wire in and out and jiggle the pin tool a bit to get the pin to release. Again with practice it becomes easier to find the sweet spot when releasing the pins.

Voila Pin removed.

I noticed on my two wire harnesses that the injector connectors had a + and a number marked on the side of the connector that the (+) wire was situated.

Image


The (+) wire is the stripped wire in the injector connector. The solid wire is the injector ground and it is the wire that goes to the ECU. If your connectors do not have any markings on them be sure to mark them before you remove the wires. Use a permanent marker and put (+) and (-) on the corresponding sides of the connector.

Where you have not done this before it may take you a bit to figure out how to get the pins to release. Don't get frustrated and try no to use too much force. it should only take a bit of pressure to release the pins.

Cheers and good luck.
not k series ( still a honda ) similar process but im sure you get the idea
